I have a 2002 s10 zr2 with 120k miles. When every the engine rpms are over 3200 there is a severe loss of power and the valves begine to chatter. I have had a k&n intake install for sometime but have had no problems untill the winter hit with -10 degree weather. There is 2 codes showing up, one for the oxgen sensor heater circuit bank2 and one for the mass air flow sensor. I have not replaced the O2 sensor yet but I did find the intake lose at the thottle body. I don't want to replace sensors that are functioning properly and I need some advice about where to start to solve this problem
have the same problem?
